Sorry to bring this back up from the dead. I am now having the same issue but worse now. Everyday the server drops the client connection at random times. There is no errors or anything that pops up. only way to establish connections is to close the lookout software and restart. IT ran wireshark and the program showed that the IP connections of the clients are still connected. I am running a total of 6258 total I/O points.
Seems we have finally figured out how to remedy the situation. The problem was with the firewall even when it was turned off. Had to allow these programs through the exceptions list and that seemed to stop the connection issues.
